So my friends back home (Saipan/Guam) are having trouble creating new accounts. When asked to verify the email, it says that they are outside the US Territory. Saipan and Guam are both US Territories. I'd appreciate it if you could take a look into this.

False, ping isn't actually terrible. Some of them (including myself) could even play USE or EU, but we do mostly play USW. And well they should correct their reasoning. It says you must be a territory of the US, which we are. Discrimination isn't cool.
